How do you identify entry and exit points in trading?

Traders develop strategies to analyse the market. For some, the strategy is to draw trend lines to identify the support and resistance. Others have a special way of reading candlestick patterns to predict the next action of the market. Some others use recent happenings in the news to predict the market action and know if to buy or sell. These are not the most effective, you should find a strategy to follow and stick to it.
